October 28, 1998 – Trespasser is released in stores around the world.
Trespasser ended up being criticized and sold very few copies, even being called worst game of the year. While some see the game as a failure, we the community do not. Many people have come and gone during the years, spreading the love of the game. Even 20 years after release the community is standing strong. During our existence we have created tons of content for the game – levels, models, fan fiction and several tools to aid us in modifying the game and create new content for it. A patch called CE Patch brought us better modern OS support among other cool contents to inspire people to create content for the game many years to come.

It is not only user made content the community have. During the years we have received original Trespasser content, including original documents, voiceover scripts, assets and early game builds, including long lost (cut) levels as Pine Valley and Plantation House.

For this anniversary we have some fun releases to share:

Update: Scallenger have released an Anniversary Edition of his Jurassic Time book, updated with some fantastic new art. You get find it on his Jurassic Time page.

Twitter Tag

Join us to spread the word on Twitter using the hashtag #Trespasser20yrs to share your story, memory, screenshots or other Trespasser related thing to the world. This one was suggested by no other than the Trespasser developer Rolf Mohr 🙂

20th Anniversary Community Level

The most important content for Trespasser’s 20th anniversary is this 20th anniversary community level. The community have manage to work together and created this amazing piece of level. It can be played from start to finish and while it might contain some unpolished parts, it is the first time in many years the community have come together to work on a level. Give it a try and have fun! If used with the CE patch, you will get an awesome custom looking sky!

Rebel’s Crossbow Contest

For the 20th Anniversary Rebel did some cool work making a working crossbow. Of course this means we will have a contest. While we are unsure of any prices it will mainly be for fun and possibly some fun special forum role (if not already a member, join our forum!! 😉 ). There are both a standalone package using the ATX patch and a version of the CE patch made by TheIdiot. Ready, aim, fire! Do not cheat 😉 Take a screenshot and share your result on our forum!

Trespasser Millennium

Over the years we have seen a few modding suites for Trespasser containing all the required tools to create your own levels for the game. First we had Trespasser CE (not to be confused with the CE Patch), and then we had Trespasser Twilight. Now we have a new, update modding suite – Trespasser Millennium.

TI’s Mega Jungle

For a few years now TheIdiot have released some versions of his Mega Jungle, a resource level that contain new content that other people can use in their levels. For the 20th anniversary, version 1.5 have been released, including “new usable Hawaiian Palms as well as the allosaurus I teased a while ago, plus a brand-new (but unfinished) willow tree, which I intend to eventually be part of a swamp-themed set of foliage. Additionally, the evergreens are now lower-poly so hopefully they won’t destroy your performance so much.”.

TI’s Trespasser Weapon Sound Overhaul

A long time ago TheIdiot did a weapon sound overhaul mod for an unknown user and have now decided to release it to the public. This can be used with ATX and CE, please see their documentation on how to use custom made TPA files.

TPA Player

Not to be confused with TPA Reader, TPA Player is what its name suggest – a TPA player. It will allow you to play Trespasser TPA files like a small media player. A simple utility for anyone who only wants to listen through the audio without export it.

For the past few weeks we’ve had some experienced some issues with the site and forum, mainly were it is impossible to upload files over 1 MB. This apply to both regular members and the staff. This means it can be difficult to attach files to your forum post or that we can’t upload any new files to the site at the moment.

Another very important issue found out recently is that you will get an error if trying to download any file from our download section. If you are in a hurry or desperate want any file, feel free to ask on the forum and we will make sure to help you out!

Please have patience as these issues (and any other we will find) get sorted out.

Experience Richard Attenborough’s masterful, nearly-lost performance of John Parker Hammond: the tragic man whose dream of bringing dinosaurs back to life came true; before being swiftly ended. Cobbled from the ill-fated Trespasser- The Lost World: Jurassic Park PC Game, and featuring amazing music by Bill Brown; you’ll feel like you’re right beside Hammond as he makes his journey across Isla Sorna, playing “God” in the laboratory, and recounting how he felt after the fateful incident at Isla Nublar. It’s a compelling and introspective tale you will never find in the novels or films.

In this special video presentation of the “Anniversary Edition”, with the immense artistic talents of Felipe Humboldt, Hammond’s words are heard against fantastic sketches that illustrate his entire story! In addition, there are numerous stills from Jurassic Park and The Lost World: Jurassic Park tinted and framed deliberately for dramatic effect. We “spared no expense”!

What also sets this edition apart from all that have come before is incredibly substantial. Thanks to the discovery of a source that contained Attenborough’s recordings; without its misty “echo/memory effects” that plagued the original and beta game files, we can now hear the vocal performance clearly for the very first time. After a decade of prior editions, and almost two decades hearing it this way straight from the game itself; this is an important milestone in perserving this experience.

The entire Hammond Memoir has been rebuilt from the ground up in order to take complete advantage of this fantastic find. Those familiar with previous editions and the game will find the clarity of Attenborough’s delivery practically startling at first. To focus on the voice, no additional sound effects were included except in two brief moments. However, there are some lines of dialogue where the sound effects mixed in by the game designers are still left in; but now in much better quality. You’ll also discover newly-created additional tracks that precede and conclude the entire program.

For an audio-only version of this entire program, plus much more, visit the website:

Fall Lodge Release

There might have been an absence of news post but surely there have not been an absence of work in the community.

Fall Lodge is a level with a small twist made by the community member Draconisaurus, crated for Halloween 2017. The level itself is not your typical Trespasser level. Its main focus is its type of mini game. In this level your goal is to gain as high score as you possibly could by killing dinosaurs. As the level title suggest, it is set in a fall theme and possibly the first Trespasser mod to be released in this theme.

Grab it now and get your own high-score. We want to hear all about it in the original forum post that you can find here.

Trespasser Online Role-playing Game

I believe this is worth mentioning as well. Over the past year, members over at our forum have played their own online role-playing game with Trespasser. It is pretty popular among some of them and I also suggest you to check this out and join in over here.

Return to Jurassic Park is still alive!

Our community member TheIdiot have worked a lot over the years with his RTJP mod. Late last year he went into the final stages of his project and are working hard on getting the first level finished, titled “RTJP~Helipad”. Be sure to check out his project here and tell him what you think so far! 🙂

Many years ago, the community received a bunch of official Trespasser assets. Among these files were an early version of Plains in 3ds Max format. Sadly this file only had foliage and the Block House, but not terrain, or textures.

The last few weeks, our forum member Draconisaurus have worked hard to make a terrain based on the height of the objects found in this 3ds Max scene. The result is really nice and it gives you an insight of what the level might have been at one point.

Intruder: Isla Sorna Demo

Some of you might remember Deagles4life’s work on remaking Trespasser in the Unity engine. He made some really nice progress and have now released a new Demo for it. The Demo can be downloaded from below.

Level download section updated!

Out download section for levels have been increased with a lot of new (old) levels. It contains various work made in the past. Some have been released before and some don’t. Machf have done great work going though his files to find old and lost fan levels.

As our download section have started to increase, work as began to make new subcategories for easier navigation. Updates on this to come.

E3 Demo Finally Found!

We all thought it was lost. We all have asked if a copy had survived anywhere out there. Would we ever see it?
Great news appeared in our forum a few weeks ago when our member Deadeyeguy_45 discovered a Tweet from no other than Seamus Blackley himself sharing his discovery of the famous E3 Demo build shown at E3 1998.

Not only that, he also found 2 other builds. A later look at those it was noted that it was an early PCGamer build (for a preview), and another copy of the E3 Demo build, so in all, 2 builds.

These versions contain the famous green T-Rex and Brown raptor. The PCGamer build also contain the long lost, and mythical level PH (Plantation House), originally located between JR and IJ. Both builds can be run and played even on modern systems (confirmed to work on Windows 10 64-bit).

After some talk with him, he was happy to share these with the public, so grab your own copy of these early builds now! You can get them HERE at our forum.

New Trespasser CE Patch

Only some time after the early build releases, Lee Arbuco reappears with a new CE patch after 2 years of inactivity. This huge update bring support for users themselves to create their own scripts for the game and some other neat functions. Be sure to grab it and check it out HERE

Jack Horner recently had an open discussion at Google. During the talks the renowned paleontologist covers several hot topics: “Jurassic World”, “Jurassic Park” & “Genetics”. The video is available right here:

New Trespasser Fan-Art

Do anyone here remember Uroš Begović? No? Some members might remember him from a few years back, when he made a fantastic fan-art cover for a Trespasser comic book (link). Sadly he never made a comic out of it, however, now he is back with some new fantastic fan-art.

Magazine Scans

As some of you might have notices, I (Tatu) have become and admin again. This means I will work on the site and the forum, and you might see some changes from time to time. I have already done some minor fixes to the main site. One thing that I have added is Hilwo’s Trespasser Combined Beta/Retail Stream.tpa Voiceover List, replacing his old ones. Head over to our Article section.

While you are there, you will see a link to a new Gallery. This is where we will place every Trespasser article from magazines that we or you find. Right now we have many added, most in non-English language. There is also an article about a programming tutorial by no other than Trespasser’s Rob Wyatt, written during the time he worked on Trespasser. Go check it out!

I have also added most of the missing videos back to the video site (now you can download them again!). They have been missing since GameSpy closed their service many years ago.

One last thing, we have turned on an extra layer of security when you register a new account (users with an existing will not notice this) on our forum in order to get control of all spambots we get. So far it seems to work without any problems, but if you have problem creating a new account, please contact us.

Everyone, including me, thought 2013’s edition of Jurassic Time (Annotated) was the final one. But it looks like since we got a 4th Jurassic Park film this year we may as well have a 4th edition of everyone’s favorite John Hammond memoir: Jurassic Time! The “Gold” edition is indeed the final one, for sure (unless we unearth pristine and uncut recordings of Attenborough’s dialogue). It removes all of the Thomas Hammond tracks from the previous release to give fans of the game a more authentic experience. You can still download the “Annotated” edition with those tracks in the archives and read up as to why they are gone from this edition. In their place are two brand-new intro and outro tracks meant to sell the idea that this all came from some old lost tapes laying around Hammond’s mansion. Otherwise all of the John Hammond tracks are identical to those from before; still in fantastic music sound quality and filled to the brim with appropriate sound effects.

I can understand those not interested in this edition since it actually offers less than before. But trust me when I say that this, to me, is the definitive way to really listen to it. Anyone who wants to experience more of the story really needs to download the “Excavated” book edition that features the entire script with pictures in a scrapbook form.

This has entire process of making all of these editions has been a labor of love for me, and I hope my final sendoff is one that will be enjoyed. Thank you all for your interest. The pleasure has all been mine. Click on the logo below to be taken to the site.
